SOLE AND STITCH REMOVING MACHINE.

Application filed December 12, 1923. Serial No. 680,124.

T 0 all whom it may concern.

Be it known that I, PAUL A. WARD, a citizen ofthe United States, and aresident of Los Angeles, county of Los Angeles, State of California.whose post-olii'ce address is 251 N. Grand Avenue, Los Angeles,California, have invented new and useful Im provements in Sole andStitch Removing Machines, of which the following is 'a specification.

This invention relates to a sole and stitch removing machine,particularly useful in a shoe repair shop, for cutting and removing thesole from the welt of a shoe, and for cutting and removing the stitchesfrom the welt in a single and simultaneous operation preparatory tore-soling a shoe.

In the consideration of this invention, reference is had to my pendingapplication for patent for sole and stitch removing machines, filedAugust 6, 1923, Serial No. 655,990.

The main object of the present invention is to provide a machinepartaking of the general form and characteristics of the machinedescribed in my said pending application but provided with oscillatablecutting and stitch. removing elements, whereas, in my said pendingapplication I have shown certain elements rotatably arranged.

A. further object of my invention is to provide a combined sole andstitch removing machine in unitary form and provided with a knifeadapted to be inserted between the welt and the sole of a shoe forcutting the stitches which hold the welt and sole together, so that thesole may be quickly removed from the shoe, together with a stitchremoving element adapted to engage the exposed portions of the stitchesimmediately after the same have been cut, for removing the cut stitchesfrom the welt.

Another object is to provide a machine of the character described,alternately operable sole and stitch removing elements adapted foroscillation or reciprocation rela tive to the sole and welt of a shoewhen the shoe is being operated upon for the purpose mentioned.

Still another object is to provide a ma chine of unitary character andcompact form and simple design for use in shoe repair shops for thepurpose described. Other objects may appear as the description progresses'.

I have shown one practicable and preferred form of device foraccomplishing the above objects in the accompanying drawing, in which:

Fig. 1 is a side elevation of my assembled machine.

Fig. 2 is a slightly enlarged front elevation of the same, partly brokenaway.

Fig. 8 is a fragmentary plan.

F l is an enlarged sectional plan of the machine as seen on line 4% ofFig. 3.

Fig. 5 is a section of same on line 5-5 of F ig. 4.

Fig. 6 is a section of same on line 6-6 of Fig. 4. V

Fig. 7 is a section of same on line 7-7 of Fig. 4:.

F 8 is a perspective view of the stitch removing tool.

Fig. 10 is a transverse section on line 10-10 of Fig. 3.

As shown in the drawing, my improved machine includes a suitable castmetal stand S which is provided with a bracket 7), on which is mounted amotor M. The upper end of the stand S has a pair of transversely alignedbosses 1 and 2, which are spaced apart and are adapted to revolublyreceive and hold an operating shaft 8. One end of shaft 3 is extendedfrom boss '1 and has attached thereto a driven pulley P which isoperatively connected by means of a belt B with a driving pulley P fixedto the shaft of motor M.

The stand Fa also has a substantially elongated boss 4-, which parallelsand is spaced from the boss 2 and is formed on the upper end of thestand. Boss 4t is adapted to receive a stud 5 which is substantiallyextended from the outer end of the boss and carries a sleeve 6 whichabuts the end of said boss. A stitch removing arm A is adjustably heldon the sleeve 6 at 1 by means of a pin 7 which extends through a portionof arm A, and the adjacent end of said arm is provided with a slot 8which overlies the sleeve 6. i

This structure described is such that the arm A may swing about the axisof pin 7 on sleeve 6 for purposes hereinbefore described.

The operating shaft 3 has its outer end in the form of a crank C With.-

inner eccentrio portion 6, an outer eccentric portion c and an.intermediate concentric portion C. The end portion. of the arm A whichis remote from the stud 5 is provided with an elongated slot 9 which isadapted to receive the inner eccentric portion 0 of crank C so as toetlect the oscillation of arm A about the axis of stud The crankoperated and of arm A. is provided with a stitch removing tool- T, asshown in Fig. Si which has base portion 10 adapted to fitoverthe end ofarm A and to be attached thereto by means of a screw 11 inserted througha suitable aperture 12. Tool T has a (ilcpending flange 1.3 whichengages the inner side of arm A so as to prevent theturning ot the toolon the arm.

The vertical portion 14; of tool 1 has a plurality of radially formedstitch rl-unovinpteeth a 25 etc, said teeth being of segmentalcross-section and having; their outer faces of convex form and adaptedto engage the stitches in the welt of a shoe after the same have beencut.

Stud 5 also pivotally carries on arm A which is similarly oscillatableabout the axis of stud. 5, and the opposite end of arm A has anelongated slot 15 which is received and held by the eccentric portion 0ol crank C. The eccentric operated. end of arm A carries a sole cuttingknife or tool T which has a knife K extended outwardly from a flat baseportion 16. Tool T is adapted to be. mounted on the end of arm A andheld by means ot a screw 17 which or;- tends through an aperture 13formed in the base of the tool anch in the case of tool T, a dependingflange 19 is provided on the base of the tool for engagement with theside of arm It, so as to hold the inner face of the knife parallel withthe operating: tacos of the switch removing: teeth A f etc.. of tool T.

' Intermediate the arms A and 5; member G held on the outer portion otstud 5 which extends th ough the bob 2'? of said guard, while the oppo.e end ot' the guard has its hub 2i ally held on the concentric portion Cof crank fluid guard however has a knife like plate cvtension 9 which isbeveled and is held in close contact with the knife K as shown in Fig.

Now it will be observed by reference to Fig. 4, that the operating:shaft 3 is substantially extended from the boss 2 on stand ,9, andadjacent said boss a collar 22 is fixedly held by means of a set screw23, while a. cuplike member D is loosely held on shaft 3 and overlies asubstantial portion of, and is slidable on collar The bore 24: of memberD intermediate the outer end 25 thereof and collar 22, is adapted toreceive a cushion E, of rubber or the like, and the arrangement of themembers 22, D and E are such that ample clearance may be providedbetween a guard the inner and of member l3 end of: boss 2. Member l) isadapted to be rotated by means of a pin 23 held in the col ar 22 andextended throiul'h an elongz'ated slot in the wall ol' .ucmhcr l).

it will -cll'l1ll that the eccentri poi lions P and c have their axes ona diamctrical line. cutting); the axis of the oncentric portion C sothat they will opcrate the arms and fl res cctivelv in opposite dircctions. The slots 9 andv 15 in members A and A prevent the morcmeutol'said arms inn-mentally but permit the movement the-rcof vertically.and the tool l will a ways move in a direction opposite to that ol tool'l".

ll hcn the shoe i held in cuglagrcnumt with. tools l and l as stated thekuilc ll will serv to cut the sole trom thc wclt. and on thesuccccdingzj movement of tool the stitches. which have been previouslycut. will be emoved from the well hf; reason of the rictional rauicnt otthe t cth f on thc tool l therewith.

is the operation piw'iarciascs the shoe is turned a that dill'ercntportions thcical; will be operated upon success vely by the tools T and'l" until the sole has bccn coup pletclv cut from the welt and thestitches have been removed.

The mechanism described is so arranged t m and T wil bc simccd apar t:ccommswlatc a miuimuo lhi lrncw: ol' solcl but fo soles of creatorthicluicss aid loos may be spread apart to a prop r cyh l'o cii'm; theshoe between and ap'aiusl hat th tools l rent he toolswhich will serveto more the inner-- u l and its tool T inwardly until the cushion wi lbe compressed to a corrospoudinn extcut while the member ll will slideover the collar so as to accommodate the mechanism to soles ofdill'crcnt thickness.

As hcreinbc'tore stated. the arm A may be further adjusted on its axis 7for more per i'icctlv accomplishing the adjustment of the tool T. Themembers A. A and (l arc opci atirclv held on the shaft 3 and stud 5 bymeans of screws Q8 and, 29 which are threadcd into the ends thereof.

It will be understood that 1' may modify and otherwise change myinvention within the scope of the appended claims without departing;trom the spirit thereof,
